Shell Programming and Scripting

Hi All,

I am having an abc.txt , which contains some digits

Eg:abc.txt

566
355

I want write shellscript in suchway that if any digit is greter than 1000 then it shuld display " text files contain digit, which is greater than 1000"


Please help me to do so

Thanks..

What have you tried so far? Are you uncertain what tool to use? Or are you just hoping that we would do your work?

Code:

for i in `cat abc.txt`
do
if [ $i -gt 1000 ]
then
echo " $i is greater than 1000" 
exit
fi
done

You should know more than one command to accomplish this, since you've already managed to create 35 posts and multiple user accounts (against the forums rules). Among these rules is that you should search the forums first for your question, so that there is less clutter. I suggest you do the same. I've moderated any other responses in this thread so far.

So please search for some keywords first, and only continue with this thread if you've got a specific problem with any of the possible solutions. We're not here to do your work, but to help you should you have troubles with anything you've learned.

Code:

$ grep "[1-9]..." infile
